LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 666,393, dated January 22, 1901.

Original application filed April 25, 1900, Serial No. 14,212. Divided and this application filed June 30, 1900. Serial No. 22,121. (No model.)

To all whom, it WZ/CLy concern.-

Be it known that I, JOHN PLAYER, a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Locomotives, of which the following is a specification.

This invention relates particularly to the means by which the locomotive is held in position upon the supporting-frame, so that compensation is provided for contraction and expansion during changes of temperature, all of which will more fully hereinafter appear.

The principal object of the invention is to provide a simple, economical, and eflicient locomotive with a boilerand supporting mechanism by which it may be yieldingly held in position; and the invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation, partly in section, of a locomotive constructed in accordance with my improvements; Fig. 2, an enlarged cross-sectional view taken on line 2 of Fig. 1 looking in the direction of the arrow; and Fig. 3, a detail plan view of the compensating-saddle mechanism which yieldingly supports the boiler in operative position, so as to permit the expansion and contraction of the same along parallel lines.

In illustrating and describing my improvements I have only shown and described those parts which I consider to be new, taken in connection with so much that is old as will properly disclose the invention and enable those skilled in the art to practice the same, leaving out of consideration other and wellknown mechanisms, which if shown and described herein would only tend to confusion, prolixity, and ambiguity.

In constructing a locomotive in accordance with my improvementsl use a boiler A of the desired size, shape, and strength and which in this particular instance is a long continuous cylindrical shell from one end to the other, though this does not form the novel element of my invention.

It is well known that the locomotive-boiler is liable to contract and expand under radical changes in temperature, so that it is desirable to provide means for taking care of this expansion and contractionthat is, compensating for itand thus preserve the efficiency of the parts. In order to accomplish this result, the frame B of the machine has 'one or more saddles 12 secured thereto, so that one or more slides C, which are secured to the boiler, may be slidingly mounted therein. The slides O are rigidly attached to the boiler-shell and provided at each end of the slide-each side of the boiler-with lugs which preferably extend horizontally beyond a vertical portion of the face of the slide, at practically right angles thereto. The saddles are provided at each end with upright angular lugs integral therewith, which interlock with the lugs on the slide and permit it to move between them as the boiler contracts or expands. These upright lugs have an angular face corresponding with the shape of the lugs on the slide, which causes the slide and saddle to have an interlocking engagement when the parts are in operative position. The saddle is also preferably provided with a pair of downwardlyextending lugs at each end, integral therewith, which form a pocket into which the side frames are closely and im movably fitted, forminga firm brace between the side frames and adapting the saddle to serve both as a brace for the frames and a support for the boiler. This arrangement of the saddle in connection with the slide portion permits the boiler to contract and expand in longitudinal lines without injury to any of the parts and at the same time secures it firmly in its seat and strengthens the locomotive-supporting frame in the manner described. The saddles are provided at each end with perforations through which bolts are inserted into the side frames in such manner as to hold the side frames firmly or immovably in the pockets on the saddle. By this means it will be seen that when the boiler expands or contracts, owing to changes of temperature, it is permitted to move in the supporting-saddles above described and substantially in parallel lines with its own axis, so as to compensate for such contraction or expansion, and thereby save the parts of the boiler or other mechanism from distortion or disruption.

I claim 1. The combination of a locomotive-boiler, a supporting-frame, and means intermediate the supporting-frame and boiler extending from side frame to side frame which forms a brace for the side frames and a saddle by which the boileris supported and permitted to move therein and thus prevent injury by expansion and contraction, substantially as described.

2. In a locomotive, the combination with the boiler-shell and with a locomotive-supporting frame, of a slide secured to the boilershell, a saddle in which the slide is slidingly mounted rigidly attached to the frame and provided with lugs integral therewith which contact and interlock with the slide, lugs integral with the saddle and rigidly secured to slidingly mounted extending from side frame to side frame and rigidly attached thereto and provided with integral lugs which contact and interlock with the slide, and lugs integral with the saddle which form a pocket for and in which the side frames of the locomotivesnpporting frame are fitted, substantially as described.
